I updated my original post with the following additional details of the movie I'm looking for:

Additional descriptive details: The movie definitely wasn't filmed in the 60s. I'm pretty sure the movie was made some time in the 70s or 80s. I'm leaning more towards the 80s, though. And yes, it was filmed in color.

I think the scene MAY have taken place in an office sort of setting, with a cage or cell built into the wall. The female victim was wearing either a dress or bathing suit.

Not completely sure, but I think there was a car chase scene directly after and there was a garbage truck involved with the chase somehow.
